Solid-State Lithium Ion Electrolytes

Abstract

Lithium-ion batteries are the state-of-the-art power sources for portable electronics, and are considered as the most promising storage systems for automotive, and even for smart grids. At present, however, they have still serious safety problems, that are chiefly due to the presence of liquid or gel flammable and volatile chemicals in the electrolyte compartment. For this reason, the search for all solid-state lithium electrolytes has gained a renewed attention. In this chapter, we discuss the three main classes which at present are under study and development: (i) ceramic, (ii) glassy, and (iii) solvent-free polymer electrolytes.
